This invention relates to an attachment for vehicles, preferably motordriven, for the purpose of spreading sand, fertilizers, crushed stone orsimilar material evenly and to any desired thickness or depth.

An object of the invention is to provide means which may be driven fromthe wheels of the vehicle for causing the material to be deliveredevenly and continuously from the vehicle while in movement. 4

A further object of the invention is to provide means whereby theattachment may be adjusted to Vary the amount of material delivered in agiven time. I

A further object of the invention is the provision of a particularspring means for regulating the even delivery of the materia A furtherobject of theinvention is to provide means for heating the deliveringroll and driving pulleys in order that the sand or other material maynot freeze thereto in cold weather and interfere with the properoperation of the device.

Other objects of the invention will be apparent from the followingdetail description and appended claims.

FLANQING MACHINE.

Application filed February 12, 1924. Serial No. 692,256.

The object of my invention is to provide a machine for forming abell-shaped flange on a head, which is to be secured to a shell bywelding.

manner, reference being had to the accompanying drawings, in which:

Fig. 1 is a sectional view showing a portion of a head having abell-shaped flange located in position on a shell so that the parts canbe connected together by welding;

Fig. 2 is a sectional view of a portion of a flanging machineillustrating the invention;

Fig. 3 is a diagrammatic plan view of the forming rolls with the rolledflange in section; I Figs. 1 to 9, both inclusive, are viewsillustrating modifications of the invention.

Referring to the drawings, 1 is a head of a boiler, tank, or otherreceptacle. The head has a dome-shaped portion 2, and a flange 3,

which is bell-shaped, or flared, as at 4, Fig. 1. 5 is the shell of theboiler, tank, or other receptacle, the end of which abuts the flaredflange, as shown in Fig. 1. The parts are welded together, as at 6.

Referring to Figs. 2 and 3, 7 designates a convexed'former and 8designates a concaved former. The head to be flanged is clamped betweenthese two formers by the mechanism common to flanging machines. 9designates a forming roller having a beveled portion 10, whichcorresponds to the flare that is desired for the bell-shaped flange.

11, 11 designate outer forming rollers that bear against the outerportion of the flange. Each roller has a tapered portion 12, conformingto the portion 10 of the roller 9. Each roller 11 is supported on abearing 13 that has a segmental rack 14:, which has a portion 15 that isadapted to a segmental guide in.a vertically sliding frame 16. On theframe 16 is a shaft 17 that has a worm 18, which meshes with the rack14. This shaft 17 is driven in the ordinary manner.

19 designates an adjusting screw for the frame 16. The upper end of thisscrew is carried by a bearing 20 on a longitudinally sliding frame 21,which can bemoved towards and from the formers by an adjusting screw 22.

The head is flanged in the ordinary manner by rolling down the flangeover the forming rollers 9. On continuing the movement, the end t of theflange 3 is flared by being rolled by the portion 10 against the beveledportion 12 of the rollers 11, producing the bell-shaped flangeillustrated in Fig. 1.

A modification is illustrated in Fig. 4, in

which the forming roller 9 is similar to the This is accomplished in thefollowing roller 9 in Fig. 2. The rollers 11 are not flanged. In thiscase, the flaring is accomplished by the portion 10 of the roller 9,while the flange proper 3 is held by the rollers 11.

Another modification is shown in Figs. 5 and 6, in which the method offorming the bell-shaped flange requires two steps. In

Fig. 5, the main flange 3 is turned down over the forming roller 9 whichis similar in shape to the roller 9 in Fig. 2. By means of a long roller11", it assumes the position shown in said Fig. 5. Then the roller 11?is moved out of the way and another frame is positioned in respect tothe flange. This frame has a double conical roller 11, which is locatedopposite the joint between the two portions of the roller 9? so as toforce the flange against the body portion of the roller 9 and againstthe flared portion 10 of the roller, producing the bell-shaped flange.

In Figs. 7 and 8, other modifications are illustrated, in which the mainflange 3 is turned down by a plain roller 11 and over a forming roller9, which is not provided with a flared portion. These two rollers aremoved away and an outside roller 11" is moved in contact with the flange3. The end of the flange is flared by means of a roller 9 that moves onan inclined axis. This roller is moved towards the flange and flares theflange while the main body of the flange is held by the roller ll asshown clearly in Fig. 9. r

In Fig. 9, the flat blankl from which the head is formed, as shown bydotted lines in Fig. 9, by being forced against a roller 11 Then theblank is pressed in shape by the two formers 7 and 8, and flanged by theroller 11 which is moved down into position opposite the roller 9 whichhas a shaped portion 10 that corresponds to the flare to be formed onthe flange.

My invention can be used in connection with a type of flanging machine,such as disclosed in the patent granted to me on July 18, 1905, No.795,180, in which the formers and the blank to be flanged are rotatedpast the forming rollers.

As illustrated in Fig. 2 of the present application, these formingrollers not only turn down the flange from the body of the blank,

Ill)

but also flare the flange to produce the bell snaped flanged head shownin Fig. 1. rleretofore, this flaring was done by hand after the ordinaryflange was formed.

I claim:

1:. The combination in a flanging machine, of formers for forming theblank to be shaped; means for Hanging the blank; and means for flaringthe end of the flange to produce a bell-shaped flanged head.

2. The combination in a flanging machine, of two formers for clampingthe blank to be flanged; means for rotating the formers and the blank;an inside forming roller having a beveled portion at its lower edge; and

i'i'ieans for bending the blank to conform to the contour of the saidforming roller to produce a bell-shaped flanged head.

3. The combination in a flanging machine, of two formers between whlchthe blank is clamped; means for rotating the formers and the blank; aninside former having a beveled lower edge; and an outside roller havinga tapered end opposite the beveled portion of the inside tormer' sothat,as the outside roller is brought into'engagement with the projectingportion of the blank, the main flange will be formed and the end of ti eflange will be flared.
